Influence of pump polarization on threshold of four-photon parametric stimulated generation of light in gases

Abstract

A theoretical analysis is made of the polarization characteristics of the four-photon parameteric generation of stimulated radiation in gases. It is shown that the parametric threshold can be increased severalfold by selecting the optimal pump polarization and the most effective resonance levels.

Influence of the polarization of radiation on the energy characteristics and threshold of stimulated Raman scattering due to rotational transitions

G V Venkin, Yu A Il'inskiĭ, G. M. Mikheev

It is shown experimentally and theoretically that the threshold intensity for stimulated Raman scattering (STRS) due to rotational transitions depends strongly on the polarization of the pump radiation. The threshold for rotational STRS is lowest for circularly polarized radiation and increases sharply for linearly polarized radiation. The results of investigations of the energy characteristics of rotational STRS on the degree of ellipticity of the pump radiation are presented.

Influence of collisions on four-photon parametric processes in gases

Э. Г. Сапрыкин, Gennady I. Smirnov

The influence of isotropic depolarizing collisions on four-photon parametric processes is considered under resonance conditions. It is shown that, in particular, there is no parametric oscillation for J = 0→1 and 1→1 transitions between levels with total angular momenta J and waves with perpendicular linear polarizations if the line-up and orientation constants are equal. A study is made of the possibility of using resonance four-photon parametric processes in the determination of the relaxation constants of multipole moments of electron shells.

Parametric oscillation in four-wave mixing with nondegenerate pumping

Gagik Yu. Kryuchkyan, K. G. Petrosyan, Karen V. Kheruntsyan

A theoretical investigation is made of parametric generation of light by four-wave mixing in an optical cavity with two pump fields of different frequencies. Mixing configurations resulting in the excitation of one and three cavity modes are considered taking into account the effects of phase modulation and of depletion of the pump fields. An analysis is made of stable steady-state oscillation regimes. Calculations are reported of the intensities of the generated radiation modes at the exit from the cavity above the threshold. An analysis is made of the conditions for the appearance of optical bistability at nonzero values of the cavity detuning.

Characteristics of stimulated Raman scattering in the presence of spatial degeneracy of levels

Yu A Il'inskiĭ, Vladimir D Taranukhin

A theoretical analysis is made of the stimulated Raman scattering in gases in the presence of spatial degeneracy of the energy levels. Saturation of the population difference and influence of anti-Stokes radiation are allowed for. Various polarizations of the pump fields and of the Stokes and anti-Stokes radiation are considered. It is shown that the profile of the stimulated Raman line is generally a sum of three Lorentzian lines and the scattering includes scalar, symmetric, and antisymmetric components. The use of circularly polarized pump radiation suppresses the influence of anti-Stokes radiation on the gain of the Stokes wave.
